STIRRUP ATTACHMENT FOR LEVER-OPERATED DEVICES.

Application filed July 21, 1913.

To all whom it may concern:

Be it known that 1, GEORGE CARL Flsrmn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stirrup Attachments for Lever-Operated Devices; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an improved stirrup attachment for lever operated devices and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

The improved stirrup attachment is primarily designed for and is shown herein as applied to a lifting-jack of the kind which is generally used in connection withautomobiles and is of especial advantage for use in such connection. It may be readily attached or detached and may be thus carried in the usual tool boX provided in an automobile or like machine and is arranged so that it may be applied not only to any kind of a lever,,but also to any part of said lever so as to make the lever to which it is applied more easily operable from any required po' sition of the operator.

The advantages of my invention will be more fully understood as I proceed with my specification.

In the drawing :Figure 1 is a view representing diagrammatically my improved stirrup attachment connected to the lever of a lifting-jack placed under the axle of an automobile frame in order to lift the same. Fig. 2 is a view representing a liftingjack in side elevation with my improved stirrup attachment applied to the end of the operating lever thereof. Fig. 3 is a detail view in elevation showing the stirrup attachment applied to a lever as in Fig. 2, but with the stirrup attachment shifted to show it in a different position. Fig. 4: is a view representing a vertical section through the stirrup attachment in a plane indicated by the line fir-'42 of Fig. 5. Fig. 5 is a perspective view of the stirrup attachment. Fig. 6 is a view representing a vertical section through Fig. 2 in a plane indicated by the line 6-6 of said Fig. 2, the section being on an enlarged scale.

Serial No. 780,148.

Referring now' to that embodiment of my invention illustrated in the drawings, 10 indicates as a whole my improved stirrup attachment applied to a lever 11 of a lifting-jack 12, the lifting-jack being of any usual and well known construction and forming no part of the present invention. The stirrup attachment 10 consists of a horizontalpedal part 13; of upright, laterally spaced, side arms or guards 14, 14; and of a confining strap 15 connecting the upper ends of said side arms 1.4:, 14. Said strap is made of leather or other suitable material and as shownhas its ends 15*, 15 looped through suitable eyes 14 14:, formed in the arms 1 1 and riveted to the main body of the strap.

The pedal part and upright side arms 14,14 are preferably stamped from a plate or bar of metal which is provided at its lateral edges with upright ribs or flanges 17, 17, which are adapted to grip the shoe of the one using the pedal. The stirrup is thus constructed as to embrace and grip the shoe of the operator so that it will move with said shoe positively both in an upward and downward direction and communicate the movement of the foot of the operator to the lever to which it is applied. 4

18 indicates a clamp attached to the stir- 'rup 10 and adapted to be connected at any point to the lever which is to be operated. Said clamp consists of upper and lower plates 19 and 20, respectively, each having flanges 19 20 adapted to be clamped together by means of bolts 21 and fiy-nuts 22 and having transversely bent parts 23, 2-1 adapted to receive and to be clamped against the lever to which the stirrup is to be applied.

The upper to the pedal clamping plate 19 is connected part or plate 18 of the stirrup by means. of a swivel joint indicated as a whole by the character 25 in such manner that said stirrup may be swung in any direction in the planeof said pedal part. The swivel connection as illustrated consists of a rivet or bolt 26 connecting the upper clamping member 19 with the pedal part of the. stirrup, there being preferably interposed between the bottom of said pedal part of the stirrup and the top of the upper clamping plate 19. one or more washers 27. In order to retain the stirrup in proper bearing relation with the upper clamping part 19 when it is shifted into a pos1tion iii-n such that its length is parallel to the length of the clamping members, the upper clamping member 19 is provided, preferably, with hearing pins 28, 28 which engage the bottom face of the stirrup plate 13.

In order to apply the improved attachment to the lever of a lifting-jack, the flynuts 22 are loosened until the clamping plates 19 and 20 are separated far enough to slip the clamping member easily upon the lever 11. In placing the stirrup attachment on the lever it is shifted to that part of the lever where the foot may be most readily applied in producing the desired operation of the lever. The fly-nuts 22 are then turned to rigidly clamp the stirrup attachment to the lever. By reason of the swivel connection between the stirrup-plate 13 and the clamping device, said stirrup may be then shifted to that position which most readily accommodates the foot of the operator no matter in what awkward position the lever may be placed, as for example, in Fig. 1, where the lifting-jack is shown as applied under the axle 29 of an automobile, back of the wheel 30, and the lever 11 has but little room at one side of the frame 31 and within the wheel for its operation.

The advantages of my improved stirrup attachment will be readily understood by those familiar with the art.

I claim as my invention l. A stirrup attachment of the kind described comprising a pedal member, an adjustable attaching member and means providing a swivel connection between said two members, the pedal member consisting of a bar bent to provide a pedal part and up right side arms, and of a flexible member connecting said upright side arms the same being spaced above said pedal part to provide a guard.

2. A stirrup attachment of the kind described comprising a pedal member, an adjustable attaching member and means pro riding a swivel connection between said two members, the pedal member consisting of a bar bent to provide a pedal part and upright side arms, said bar being provided with gripping ribs, and of a flexible member connecting said upright side arms the same being spaced above said pedal part to provide a guard.

3. A stirrup attachment of the kind described comprising a pedal member and an adjustable attaching member, said attaching member consisting of spaced upper and lower clamping plates and of clamping bolts and nuts, means pivotally connecting the upper clamping plate to said pedal member, and means attached to said upper clamping plate providing a bearing for said pedal member as it is swung on said pivotal connection.

In testimony, that I claim the foregoing as my invention I affix my signature in the presence of two Witnesses, this 19th day of July A. D. 1913.
